5 Claims.

My present invention relates to a hinge which is particularly suitable "for use with certain typ of windows and the like.

The main object of my invention is to provide a hinge of the kind indicated adapted to exert a braking efiect on the window-sash during the opening movement or part thereof.

Another object of the invention is to provide a hinge of the type indicated which is adapted to cause an increase of the braking effect with increasing opening of the window.

An embodiment of the invention is illustrated in the accompanying drawing in which- Fig. 1 shows an elevation of the hinge'mounted on a window,

Figs. 2 and 3 show perspective views of the two main hinge parts,

Fig. 4 shows a partial sectional view of a detail of a slightly modified embodiment, and

Fig. 5 shows an elevation of the window on which the hinges are used in this instance.

In the embodiment of my invention shown in the drawing a member A is secured to a windowframe I at each bottom corner thereof. Said member A forms one main part of the hinge and comprises a portion 2 provided with holes 3 for screws 4 securing said member A to the window-frame I. Said portion 2 is provided with a semicircular flange 5 projecting perpendicularly thereto and having a hole 6, the object of which will be set forth below.

Another member B of the hinge is secured to the window-sash H! by means of screws ll penetrating through holes l2 in a portion I3 of said member B. A flange M of said member B projects perpendicularly to the portion l3 and is provided with a pin l'5 registering with and fitting in the hole 6 in the flange 5 when the window-sash l occupies its proper position in the window-frame I. In the embodiment shown the flange i4 is approximately demi-semicircular but this shape is, of course, not obligatory.

Flange is provided with corrugations I5 covering the entire flange or only part thereof, and forming the stepped portions ofiset from the plane of the flange, as shown in Figs. 1 and 3. One of the flanges 5 01 I4 may be provided with a peripheral flange which is, in this case, provided on the flange l4 and bears the reference letter [8. between the flanges '5 and I4 and, therefore, improves the appearance of the hinge.

The window, in this case, is of the type shown diagrammatically in Fig. 5. When the windowsash is being opened, it turns on the pivots I5 Said flange l8 covers the slot and thereby the flange l4 slides against the surface of the flange 5. The shape of said flanges, as described above, causes increased friction between the flanges, the lower down onto the bent portion of flange 5 the other flange I4 is being moved. Thus, when the tendency of the window-sash Hi to swing downwards is progressively increasing, the braking effect of the hinge is also automatically increasing. Preferably the braking effect should be adjusted so as to enable the window-sash to be maintained in any position by said braking effect alone. Of course, the braking part of the flange 5 can be resilient, if desired.

The member A can be provided with a slot l9 allowing the introduction of the pin I5, and said pin l5 can have a head 20 for maintaining the plates 5 and I4 in close engagement with each other.

It should be evident that numerous modifications of the embodiments described are feasible within the scope of the invention and, therefore, they must not be. considered in any limiting sense whatsoever. They are only for the purpose of explanation of my invention.

What I claim is:

1. In a hinge of the character described having two parts, a pin pivotally connecting the parts together, a plate-like member associated with one hinge part and lying in a plane perpendicular to the axis of the pin, and contact means carried by the other hinge member in sliding engagement with one surface of said plate-like member, said plate-like member having an extension provided with a plurality of stepped portions each lying in planes parallel to the plate-like member, said stepped portions progressively offset out of the plane of the platelike member toward the contact means to exert greater pressure on the contact means axially of the pin when the hinge parts are relatively pivoted to bring the contact means and offset extension into engagement with each other.

2. In a hinge of the character described having two parts, a pin pivotally connecting the parts together, a plate-like member associated with one hinge part and lying in a plane perpendicular to the axis of the p a d contact means carried by the other hinge member in sliding engagement with one surface of said plate-like member, said plate-like member having a resilient extension provided with a plurality of stepped portions each lying in planes parallel to the plate-like member, said stepped portions progressively offset out of the plane of the plate-like member toward the contact means to exert greater pressure on the contact means axially of the pin when the hinge parts are relatively pivoted to bring the contact means and ofiset extension into engagement with each other.

3. In a hinge of the character described having two parts, a pin pivotally connecting the parts together, a plate-like member associated with one hinge part and lying in a plane perpendicular to the axis of the pin, and contact means carried by the other hinge member in sliding engagement with one surface of said plate-like member, said plate-like member being provided with a plurality of stepped portions each lying in planes parallel to the plate-like member, said stepped portions progressively offset out of the plane of saidplate-like member toward the contact means to exert greater pressure on the contact means axially of the pin when the hinge parts are relatively pivoted to bring the contact means and stepped portions into engagement with each other, said contact means comprising a plate juxtaposed to the plate-like member and lying in a plane parallel with one hinge part and lying in a plane perpendicular to the axis of the pin, and contact means carried by the other hinge member in sliding engagement with one surface of said plate-like member, said plate-lik member being provided with a plurality of stepped portions each lying in planes parallel to the plate-like member, said stepped portions progressively offset out of the plane of said plate-like member toward the contact means to exert greater pressure on the contact means axially of the pin when the hinge parts are relatively pivoted to bring the contact means and stepped portions into engagement with each other, said stepped portions of the plate-like member being resilient.

5. A hinge of the character described comprising a pair of juxtaposed parallel plates, a pin pivotally connecting said plates together, means for securing one plate to a frame, means for securing the other plate to an element pivotally mounted in said frame, and one of said plates having a plurality of progressively stepped offset portions parallel to the planes of said plates adapted to be engaged by the other plate when said plates are pivoted relatively to each other to progressively increase resistance to relative pivotal movement between said plates.
